A model illustrates that PM activates the SREBP1-PIR/inflammasomes signaling axis through SIRT1 -mediated modulation. (A) A schematic model to describe the positive feedback loop and detailed mechanisms of the SIRT1-SREBP1-PIR axis and crosstalk with NF-κB signaling. (B) SIRT1 modulates the SREBP1-PIR/NLRP3 inflammasome axis in response to PM. SIRT1 functions as a protector from PM exposure. The SIRT1-SREBP1-PIR/NLRP3 inflammasome axis may present an attractive therapeutic target for PM-related adverse health events.
